ROBERT H. HEY, OF PHILADELPHIA, PENNSYLVANIA.

STRAINER FOR WATER AND OTHER FLUIDS.

SCIFEOA'ION 'orming part of Letters Patent No. 338,523, dated March 23, 1886.

Application filed Dcccmbcr 2S, 1885. Serin] No. 186,867.

To @ZZ whom, it may concern.-

Beit known that I, ROBERT H. HEY, a citizen of the United States, residing in the city and county ofPhiladelphia, State ofPennsylvania, have invented a new and useful Improvement improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l represents a longitudinal section of a strainer embodying my invention in line x a', Fig. 2. Fig. 2 represents a longitudinal section thereof in line y y, Fig. l. Fig. 3 represents'a transverse sect-ion in line .e z, Fig. 2.

Similar letters of reference indicate corresponding parts in the several gures.

My invention consists of a strainer for water and other iluids, in which provision is made for readily cleansing the same without stopping the iiow of fluid through the device.

Referring to the drawings, A represents a shell,which is of cylindrical form, and open at both ends, and provided with inlet and outlet branches B B at the sides.

O represents a cylinder orstrainer chamber, which is fitted within the shell A, and made longer than the same, the ends of said chamber being closed by heads D,which are held in position by yokes E,whose ends are formed with hooks or inwardly-extending lugs F,which engage with flanges G on the chamber, the crowns of the yokes being tapped to receive screws GQ which bear against the heads D, and when tightened clamp the latter firmly against the ends of the chamber C, thus reliably closing the same. Within the chamber is a perforated diaphragm, I-I, and a division-plate, J, the diaphragm Hextending thelength of the chamber from one head to the other close against the same, the division-plate separating` the chamber into compartments K L, which are not in communication.

In opposite sides of the wall of the chamber C, and on opposite sides of the plate J, are ports M N, which are so disposed that each pair of ports may be placed in communication with the branches B B of the shell A by moving the chamber G.

Connected with the iianges of the chamber C is a rack-bar, P,with which meshes apinion, Q, the axis of the latter having bearings R, secured to the shell A. One of the branches is (No model.)

connected with a supply-pipe, and the other With a pipe leading to the place of service.

According to the position of parts shown iu the drawings, referring more particularly to Fig. 2, the iiuid tirst enters one side of the compartment L and passes through the diaphragm thereof, reaching the opposite side of the compartment in strained condition, and so escapes through the discharge branch. Should the diaphragm or the receiving side of the compartment be clogged with sticks, leaves, dirt, &c., the same may be cleansed as follows: The pinion Q is operated byits handle S, whereby the chamber@ is shifted, and the ports N N are placed in communication with the branches B, and thus the tluid iiows into the compartment K, where it is strained, and whence it escapes, the operation being` accomplished without stopping the flow orsnpply of fluid to the strainer. The head ol' the compartment L is now removed, and the said compartment is accessible, whereby the matters therein may be removed, the plate J, asis evident, preventing the tluid which fiows through the diaphragm H from entering said compart4 ment L. Vhen the compartnientKor its diaphragm becomes clogged or filled with improper substances, the head of the compartment L being previously restored the chamber C is again shifted, so the ports M are again in communication with the branches B B. The head ofthe compartment K is now removed, and the interior of said compartment and its diaphragm are accessible.

For convenience ot' cleansing the parts the diaphragm is made in sections, each section being separate from the divisional plate, so as to be readily displaced when the proper head is removed.

Having thus described my invention, what I claim as new,and desire to secure by Letters Patent, is-

l. A strainer having the outer shell, A,with branches B B on opposite sides, and the shifting-cylinder C, having ports M M and N N, substantially as described.

2. In a strainer, the shifting-cylinder C, provided with ports M M and N N, divisionplate J, and diaphragm Il, in combination with the outer shell, A, having both an inlet and outlet port, substantially as described.

3. A strainer having inlet and outlet open- IOO ings, and a shifting straining-Chamber formed in divisions, each provided With ports Which may be placed in communication With said openings and permit the straining of uid Without stopping` the flow of the same While shifting the straining-chamber, substantially as described.

4. A strainer-chamber formed in sections separate from each other, each provided with ports, and an exterior shell Withinlet and'outlet openings, sa-id chambers having detachable heads and made movable Within said shell, substantially as described. c
